2019-07-23ELF final_write_processingAlan Modra1-1/+2
Move setting of OSABI to final_write_processing, after symbols are written. This allows OSABI to be set based on symbols actually written to the output rather than assuming input symbols will be output. Corrects object files such as the one generated on powerpc64le-linux by ld-powerpc/pr23927.s which has a local STT_GNU_IFUNC symbol but prior to this patch the file was marked ELFOSABI_NONE. * elf-bfd.h (enum elf_gnu_osabi): Rename from elf_gnu_symbols.

2018-10-08Separate header PT_LOAD for -z separate-codeAlan Modra1-42/+46
This patch, along with previous patches in the series, supports putting the ELF file header and program headers in a PT_LOAD without sections. Logic governing whether headers a loaded has changed a little: The primary reason to include headers is now the presence of SIZEOF_HEADERS in a linker script. However, to support scripts that may have reserved space for headers by hand, we continue to add headers whenever the first section address is past the end of headers modulo page size. include/ * bfdlink.h (struct bfd_link_info): Add load_phdrs field. bfd/ * elf-nacl.c (nacl_modify_segment_map): Cope with header PT_LOAD lacking sections. * elf.c (_bfd_elf_map_sections_to_segments): Assume file and program headers are required when info->load_phdrs. Reorganize code handling program headers. Generate a mapping without sections just for file and program headers when -z separate-code would indicate they should be on a different page to the first section. ld/ * ldexp.c (fold_name <SIZEOF_HEADERS>): Set link_info.load_phdrs. * testsuite/ld-elf/loadaddr1.d: Pass -z noseparate-code. * testsuite/ld-elf/loadaddr2.d: Likewise. * testsuite/ld-i386/vxworks2.sd: Adjust expected output. * testsuite/ld-powerpc/vxworks2.sd: Likewise. * testsuite/ld-elf/overlay.d: Remove spu xfail. * testsuite/ld-spu/ovl.lnk: Don't use SIZEOF_HEADERS. * testsuite/ld-tic6x/dsbt-be.ld: Likewise. * testsuite/ld-tic6x/dsbt-inrange.ld: Likewise. * testsuite/ld-tic6x/dsbt-overflow.ld: Likewise. * testsuite/ld-tic6x/dsbt.ld: Likewise.
